6 Claims; (01. 155-178) This invention relates to a base for'supportinga cushion on a furniture frame and more particularly to a base which ismade of a single piece of sheet metal and supports'a resilient or springcushion in a frame for furniture which is of rectangular form, such aschairs, sofas, settees and the like.

It is the object of this invention to provide a base of this characterwhich is not only simple and durable in construction but also forms astrong and reliable support for the cushion and also serves to rigidlyconnect the several members of the frame and utilize the material usedto make the base'to greater advantage without any increase in the costof production and thereby eifecting a substantial economy in manufactureand also producing a'superior product.

In the following description similar characters of reference indicatelike parts in the'several figures of the drawings. v v

The frame of the furniture upon which the cushioning means are mountedby means of this invention is preferably made of wood in the form of arectangle and comprises horizontal longitudinal front and rear rails 20,2| which are spaced from each other, horizontal transverse side rails 2223, also spaced from one another, and vertical front and back stumps 24,25, each of which is connected with the adjacent ends of a longitudinalrail and a transverse rail and forms one and the stumps is effected bymeans of dowels 25, but this may be accomplished in any other suitablemanner.

The base which supports the spring cushion or other form of cushion inaccordance with this invention, is constructed of Y a single sheet ofmetal so that its several members are integrally connected and in itspreferred form the same is organized and mounted on the frame asfollows:

The numeral 2'! represents the bottom or bottom plate of the base whichis of rectangular form and arranged horizontally within the lower partof the frame.

At its front and rear longitudinal edges this bottom is provided withfront and rear vertical Walls 28, 29 which project upwardly from thebottom and at its transverse side edges the bottom is also provided withvertical transverse walls 3n, 3! which project upwardly from the bottom,the several walls terminating at their upper edges flush with the top ofsaid rails and forming with the bottom a structure having the generalshape of a pan or tray.

The front and rear walls of the base are provided, respectively, attheir upper edges with hangers forming part of the means for mountingthe baseon the frame, each of these hangers having the general shape ofa hook in cross section and comprising a horizontal longitudinal web 32projecting outwardly from the respective wall and engaging with the.upper side of the respective longitudinal rail, and a flange 33projecting downwardly from the outer edge of said web and engaging witha rabbet 34 on the upper outer corner of said rail, as shown in Figs. 1,4 and '7.

Each of the front and rear walls of the base is secured to the innerside of the adjacent longitudinal rail of the frame by fastening meansconsisting preferably of screws 35, as shown in Figs. 1, 6, 7 and 9.

Each of the transverse side walls 22, 23 of the base is spaced from theadjacent transverse rail of the furniture frame and provided at itsupper edge with a reinforcement or stiffening member which comprises ahorizontal web 36 projecting outwardly from the respective wall andprovided with a vertical flange 31 projecting downwardly from the outeredge of this web, thereby strength- 'en'ing this wall and preventingdistortion of the jecting coupling tabs 42, each of which is con nectedwith the inner side of the adjacent lip 35 by spot welding, as shown at43 in Figs. 2, 3 and 9. The several members of the base are preferably 4at its opposite ends with lips extending in the same plane therefrom andconnected with the adjacent stumps, and coupling tabs arranged atopposite ends of each of the other two walls and each tab projectinglaterally outward from the respective wall and connected with theadjacent lip.

3. An integral sheet metal base for supporting a cushion on a furnitureframe having front, rear and side rails and stumps-at the cornersbetween said rails, said base comprisin a horizontal bottom, verticalfront, rear and side walls formed from a single sheet of metal ofrectangu- I lar outline, as shown in Fig. 10, by providing this blankrespectively on its two longitudinal edges with short transverse slits44 adjacent to the corners of the sheet, also providing the transverseedges of the same with short longitudinal slits 45 adjacent to thecorners of the sheet, and also providing the transverse end. portions ofthe sheet with outwardly off-set slits .45, each of which formsaninwardextension of one of the longitudinal slits 45..

After the blank sheet has been thus cut, the front and rear longitudinaledge portions are bent upwardly along the lines 41 to form the ,frontandrear walls28, '29 and'the lips 38, and the transverse edge portions ofthe blank are bent upwardly along the lines 48 to form the transversewalls 30, 3!. .The front and rear longitudinal edge portions of theblank are also bent along the lines 49, 50 to form the front andrearsupporting hooks of the base, and the transverse edge portionsof theblank are bent along the lines -5l, :52 toform the reinforcing membersof the base. The end portions of the lips 38'are bentalo'ng the lines 53to form the flanges 40, and the :end portions of the walls 3!], 3| arebent along the lines 53 to form the flanges 40, and'the end portions :ofthe-walls 30, 3! are bent along the lines 54 to form the tabs 42.

In this manner all the'material of the blank I is usefully employed toproduce a strong and efficient base for supporting the cushioning offurniture at relatively low fabricating cost and without waste ofmaterial. Moreover, this invention not only forms a "stronger connectionbetween the base and the furniture frame but it also firmly and rigidlycormects the rails "and stumps at each corner of the frame so as toreliably hold them 'together and thus strengthen the furniture as awhole.

I claim:

1. An integral sheet metal base for supporting a cushion on afurn'iture'frame having front, rear and side rails and stumps at thecorners between said rails, said base comprising a horizontal bottom,vertical front, rear and side walls projecting upwardly from thecorresponding edges of said bottom, andtwo ofsaid'walls' being mountedon the adjacent rails and each provided at-its opposite ends with lipsextendingin the same plane therefrom and connected with the adjacentstumps.

2. An 'integralsheet-metalJ-base for supporting a cushion on a furniture{frame having front, rear and *side rails-and stumps at the cornersbetween said rails, said base comprisinga horizontal bottom, verticalfront, :rear and side walls projecting upwardly from the correspondingedges of said bottom,-:and ftwo ofsaid wallssbeing mounted onthe-adjacent rails and each'provided projecting upwardly from thecorresponding edgesof said bottom, and two of said walls being mountedon the adjacent rails and each provided at its opposite ends withextensions, each of which forms a lip arranged in the same plane as therespective wall and connected with the adjacent stump and a flangearranged on the outer end of the respective lip and projecting at anangle therefrom and connected with the adjacent framerail.
